CodeRage 4 is a free, virtual conference on Embarcadero technologies with a lot of Delphi sessions.
It is held from September 8 till 11, 2009, i.e. while I write this :-)
If you want to watch sessions live, be sure to register through LiveMeeting (the technology they use for making this all happen).

Let me know if you download, and what you are using the sample code for.
